Your concern I believe is with M15, aka "motor" (component)15. X644, aka "connector" (component)644, is what electrically connects to this locking device.


Hopefully you know how to read and interpret wiring diagrams and schematics.

You should have something very similar to this:

^^^look for "M15" and observe how it's electrically connected.


And THEN...you can interpret from the pinouts what they might be from this:

Pin assignments at plug connector X254
Pin Type Description /Signal type Connection /Measuring notes
1 M Terminal 31 Power ground Ground point
2 A Open window signal Power window motor, rear left right-hand drive Power window motor, rear right
3 A Signal, switch off consumer load Connector, switch off consumer load
4 E Terminal 30 Fuse F60
5 A Open window signal Power window motor, rear right right-hand drive Power window motor, rear left
6 A Central arrest signal ZV motor drives, rear doors
7 A Unlock signal Motor, bottom tailgate
8 Not used
9 A Servotronic activation Electrohydraulic converter of servotronic
10 E Terminal 30 Fuse F27
11 A Measuring resistor, Servotronic Electrohydraulic converter of servotronic
12 A Close window signal Power window motor, rear left right-hand drive Power window motor, rear right
13 A Lock ZV ZV motor drives, rear doors
14 A Unlock signal ZV motor drives, rear doors/tank flap
15 A Close window signal Power window motor, rear right right-hand drive Power window motor, rear left
16 A Activation, luggage compartment light Luggage compartment lights
17 A Activation, courtesy lighting Front zone lighting
18 A Pump signal Washer pump
19 A Signal, switch off consumer load Connector, switch off consumer load
20 A Interior lights signal Entry light module



We're interested in the "central lock" related wiring. Or maybe the word "unlock" to help drive that actuator.
Look here if you get confused:

Hopefully someone else from this forum can chime in with more specific detail. ......hopefully.
